哈尔滨理工大学学士学位论文 LED新型智能台灯
摘要
随着时代发展，节能环保、健康与人们的日常生活变得密不可分，科技的进步，也使家电更加智能化和人性化。台灯作为家电中基础的，也是必不可少的，所以，提出LED新型智能台灯设计。
该设计是以STC89C52RC单片机为控制核心的集多种功能于一体的智能LED台灯。该台灯实现了自动检测屋内是否有人并自动开启/关闭功能；台灯光亮度具有手动、自动两种调节方式；具有时间、日期显示功能，休息提醒和坐姿纠正等多个功能。硬件设计部分分为单片机控制模块、按键模块、照明模块、光敏模块、坐姿纠正模块、视力保护模块、时钟模块、显示模块，红外传感模块等多个部分。单片机主控制芯片选用STC89C52RC，显示模块选用LCD1602，通过按键模块来调整时间、日期、LED的亮度，时钟芯片选用DS1302，照明模块选用16颗高亮度白光LED，休息提示用蜂鸣器发出闹铃提示音，检测用户选用BIS0001红外热释传感器。通过单片机C语言编程进行软件设计，综合实现了全部控制功能。

哈尔滨理工大学学士学位论文 New intelligent LED lamp
Abstract
With the development of the times, energy saving and environmental protection, health and people's daily life has become inseparable. Advances in technology, but also makes home appliances more intelligent and humane. Stands as the foundation of home appliances, is also essential, therefore, propose the design of new intelligent LED lamp.
This design is based on STC89C52RC microcontroller, which is the core of controlling and sets a lot of functions in one smart LED lamp. The design achieves the function of automatic detection of whether someone in the house and automatically turning on / off; The light levels with manual and automatic adjustment mode; Has the time, date display function, resting posture corrective reminders and many other functions. Hardware design part is divided into single-chip control module, the key module, lighting modules, photosensitive module, sitting correction module, eye protection module, clock module, display module, infrared sensor module and many other parts. The main control chip microcontroller selects STC89C52RC, display module selects LCD1602, through key module to adjust the time, date, LED's brightness, clock chip selects DS1302, lighting modules uses 16 high-brightness white LED, buzzer alarm with the rest prompt tips tone, detect user selects BIS0001 infrared pyroelectric sensors. By Microcontroller C programming language to finish software design, integrated to achieve full control.
